Use in C ++

// When using C language or CPP to create an array, a large number of new and delete operations are used, which is unpleasant.
// Use <array> instead. It is very convenient. It is the same as STL <vector>.
// Execution efficiency is higher than <vector>, which is almost the same as int myarray [5 ].

// Save the following code as testarray. cpp, In the UTF-8 format, compiled using mingw:

// G ++ testarray. cpp-STD = C ++ 0x
